New forms of free weights for weight training are provided. Such free weights may include a flexible, gripping ring set in a channel with a varying width, configured to be threaded over the end of a barbell. The channel may include a locking notch. Such a free weight may be rotated until the channel is aligned with a floor (perpendicular to gravity) and then loaded onto the barbell by threading the gripping ring onto the barbell. The free weight is then rotated 90 degrees causing the barbell and gripping ring to travel away from a center of the channel, where the channel narrows and includes the locking notch. The gripping ring is resultingly deformed by the narrower section of the channel entered, into an ovoid shape, gripping the barbell by force of gravity. A user may then reverse these steps, to release and unload the free weight from the barbell.

The present application relates to a kind of free weight training monitoring method using wearable PPG sensor, belong to mobile computing application and human training auxiliary technical field.The present application uses infrared light and green light on PPG sensor to irradiate wrist skin, and collects the optical density change data containing muscle movement information.By analyzing change data, the load weight currently used by exerciser, the number of repetitions and the type of movement are obtained, and further predict the adjusted load weight required in next step.The present application proposes a novel arterial noise elimination method, effectively reduces the influence of pulse noise in artery, designs a novel feature extraction method based on recurrence plot, maps each action segment to two-dimensional phase space to extract space-time features, and constructs a novel multi-task learning model based on convolutional neural network.The present application can effectively identify load weight and movement type, realize the monitoring of free weight training.

A modular and configurable muscular physical rehabilitation and training system that is a total body fitness system designed to promote strengthening and creation of muscle mass using free weights. Free weights simulate real-life situations and promote whole body stabilization. Free weights allow more variations in the range of motion than using modern machines. The system allows the flexible and configurable use of muscle contractile activities utilizing free weights and proper techniques. This is done in a space-saving, compact, safe, configurable, and practical configuration that can be used with a plurality of participants supported by a single trainer / therapist.

An intelligent weightlifting apparatus includes a frame including vertically oriented members and safety rails that are selectively moveable up and down relative to the vertically oriented members. The apparatus includes a position sensor that is configured to detect a position of a barbell. The apparatus includes a computer that is configured to control movement of the safety rails based on data from the position sensor such that a predefined distance is maintained between the safety rails and the barbell during a free weight exercise.

An apparatus for enabling a spotter to assist a lifter in a weight lifting exercise comprises a clamp for removably attaching to and enclosing a bar for free weights in an interior therein, the clamp securely retaining the bar along a length of the clamp, the bar being lifted by the lifter during the weight lifting exercise. The clamp is securely and removably attachable to a cable at an attachment end of the cable, the cable being disposed about a wheel of a pulley that is anchored to a stable point. A free end of the cable is manipulable by the spotter to selectively operate the pulley to assist with raising and lowering the bar.

A detachably attachable weight clip system includes a weight clip for mounting a free weight to a barbell. A weight clip may be configured on either end of a barbell and weights can be hung from therefrom. A weight clip has a mounting collar that is configured to slide over the end of the barbell and a hook that extends from the mounting collar forming a cradle to receive a weight therein. The hook may be configured to rotate with respect to the mounting collar to position the weight hanging from the hook and a swivel lock may enable a user to lock the hook in a rotational position with respect to the mounting collar. A collar set screw is configured to secure the mounting collar in a fixed position along the barbell and a hook set screw prevents the weight from being dislodged from the hook during exercise.

An exercise apparatus including an outer handle, a rod arranged to rotate within the outer handle, a first weight plate with an opening at an upper region, and a second weight plate with an opening at an upper region, where the first weight plate is attached to the rod by a first bolt and the second weight plate is attached to the rod by a second bolt.

A multi-modal strength training apparatus facilitates simultaneous use of free weights and resistance band training modalities, the apparatus including a frame body having a faceplate defining a vertically planar configuration having opposed ends and upper and lower edges. A pair of support walls extend upwardly from opposed ends, respectively, and a pair of upper receiver members each having an elongate inverted U-shaped configuration are coupled to upper ends of the support walls, respectively. The apparatus includes a pair of hook members coupled to a lower extent of the frame body and are configured to cradle or connect to a resistance band. In use, the upper receiver members are configured to receive a barbell and to avoid interference with a user's grip thereon while the faceplate defines an opening for receiving a fastener and resistance band.

A high-position pull-down handle is arranged on the front side of the middle of a front transverse frame, pull-up handles are arranged on the two sides of the front transverse frame, a bird chest clamping handle is arranged on the front side of the top of a Smith sliding rail, and a free weight training hook is arranged on the upper portion of a middle frame; the first guide rail and the second guide rail are provided with an overhead type sitting posture chest clamping and pushing device, and the overhead type sitting posture chest clamping and pushing device has the sitting posture chest clamping and pushing functions. A non-fixed openable Smith suite and an L-shaped parallel bar arm flexion and extension bracket are arranged on the Smith slide rail; and non-independent rowing machines are arranged on the rear bottom cross frame and the rear middle cross frame. The problem that functional parts of a traditional product are simply stacked is solved, and through the improved design of the structure, various devices can have multiple purposes and can be used / called by different functional parts; the functions are more complete, the moving trajectory is smoother, and the trajectories of different devices are not overlapped and interfered; the structure is simple and convenient, the total weight is reduced, the use space is reduced, and the production, configuration and use cost is reduced.
